(Vector) Glueballs and Charmonium Decay Revisited

Abstract

From the $0^{++}$ glueball candidate we argue that the $1^{--}$ glueball $O$ to be near in mass to $J/ψ$. This is supported by the recent null search for $ψ^\prime \to ρπ, K^*\bar K$, while absence of distortion in the energy scan of $J/ψ\to ρπ$ indicates that $Γ_O \gg Γ_{J/ψ}$. $O$ may also play a role in the OZI violating $\bar p p \to ϕγ, ϕπ$ production puzzle.
